ADJUSTABLE STOP FOR SLIDING DOORS.

SPECIFICATION forming part of Letters Patent No. 333,281, dated December29, 1885.

Application filed November 3, 1885. Serial No. 181,779. (No model.)

To all whom; it may concern:

Be it known that I, JOHN B. (Drums, of Aurora, in the county of Kane andState ofIllinois, have invented certain new and useful Improvements inAdjustable Stops for Sliding Doors; and I do hereby declare that thefollowing is a full, clear, and exact description of the invention,which will enable others skilled in the art to which it appertains to [0make and use the same, reference being had to the accompanying drawings,and to letters of reference marked thereon, which form a part of thisspecification.

My invention will be readily understood from the following:

I Figure l is a side elevation of two sliding doors in the position theyoccupy when closed together, and also of part of the rail or track,sufficient to illustrate my invention as applied to the same; Fig. 2, across-section'on a larger scale in the line :0 m of Fig. 1, and Fig. 3details on a larger scale.

The invention may be used with any hanger that is fitted to slidingdoors; and it consists of two parts, one of which, A, is screwed firmlyto the under side of the rails B, and of plates 0, secured severally tothe top of each door close to its outer vertical edge, as shown, andthese parts A and O, with their peculiar features, next to be described,constitute the stop.

Plate A has a downward projection, D, made integral with it, and it isprovided with two vertically-adjustable screws, E E, whose heads may beregulated to project a desired distance below the lower line ofprojection, D, for a purpose presently to be stated.

Each plate 0 has an upward projection, c, and each of these projectionsis drilled to receive a buffer, E, which is preferably made of rubber orleather, these two buffers facing each other-that is, the buffer on onedoor faces that on the other door.

The office andduty of the adjustable screws 45 E E is to prevent thedoor from jumping upward if on sliding the door outward it is broughtagainst the projecting part I) of plate A with too much force, it beingunderstood that this plate is so located on the rails B 50 that whenboth doors are closed to meet each other their line of meeting (marked 3shall be about beneath the center of the projection D, and when in suchposition the adjustable screws E shall be over the doors, near theirinner top corners, as seen, there being one of 5 these screws for eachdoor.

The ends 0 of plates 0 preferably extend far enough beyond the upwardprojection c to pass under the heads of. screws E when the doors areclosed.-

The buffer F for each door breaks the force of the blow caused bybringing the door against the stop or projection D, and in this positionit is held until the other door is brought up to it, when, of course,both doors are closed.

If the partitions of the apartments settle or if a carpet is to beremoved, or if for any reason the doors need to be vertically adj usted,the screws E are then also to be vertically adjusted accordingly, sothat if the door should happen to be brought against the stop D withgreat force it cannot jump or rebound upward. This adjustment of thescrews may be made very fine, leaving barely room enough for the forwardend of plates 0 to pass under their respective screws withoutobstruction from them. 7

By my construction I dispense with any iron buttons or other solidpieces usually placed on the back inner edge of the door, within thepartitions of the wall, and avoid the bad effects of such construction,among which may be named the following, to wit: one door or the otherbeing always closed first, the button or other solid piece comes up witha bang or sudden shock, which soon breaks them off or pulls out thescrews which hold it, besides causing the door to jump up and often tothrow the wheels off the track; again, the striking-pieces of thesebuttons must be put in place and fastened before the lath and plaster ofthe partition are put on,and therefore when the button is torn off thereis no replacing it, and the door is consequently always out of order;and, further, doors are generally made from one and a quarter to fourinches thick, and the manufacturer must supply with these stop-buttonsfor all the different thicknesses of doors.

By my improvement the plate A is centrally placed at a point above thatwhere the closed doors meet. The adjustable screws E E are. easilyaccessible for adjustment at all times.

My above-described devices may be made of.

one and the same size for all sliding doors; in

other words, adapted for doors of any custon1 ary thickness. 5 In thedrawings, G indicates the hangerwheels which run upon tracks B; H, theaxle common to both these wheels, and J the riderbar, and which partsneed no further description.

I would again repeat that although by way of clearness of illustration Ihave shown my improvements as applied to one style of hanger havingdouble wheels and double tracks, yet the invention is applicable todoor-hangers x 5 generally.

I claim-- 1. An adjustable overhead center stop for sliding doors,consisting of a center plate adapted to be fixed on the under side ofthe track or rail and having a downward projec- 20 tion provided withadj ust-able screws, combined with a plate adapted to be secured to thetop of the door and having an upward projection provided with a bufleradapted to come in contact with said downward projection, as and for thepurposes set forth.

2. The described stop for sliding doors, consisting of the fixed plate BI), having the adadjustable screws E E,and centrally afiixed to thetrack, as set forth, combined with the plates 0 0', one on each door,and each provided with a buffer, F, the combination being and operatingsubstantially as set forth.
